Hydraulics is a sub-discipline of Civil Engineering. It deals with all types of fluids, especially water, at rest or in motion, by widely using the fluid mechanics. Hydraulics is a discipline which applies the principles of fluid mechanics to problems dealing with the collection, distribution, storage, transport, regulation, measurement, or briefly management of water. Therefore, fluid mechanics is one of the main subjects of civil engineering.

Hydraulic engineering deals with pipe flows, in which the fluid is transported under pressure, as well as rivers, channels, lakes, estuaries and ocean free-surface flows. In addition to the water flow, atmospheric air flow also becomes important as to understanding the interaction with the civil engineering structures.

The hydraulic engineer provides designs for various structures which interact with water such as dams, ports, outlets, canals, related structures for irrigation and drainage projects, pipelines, water supply networks, storage tanks, waterways, water intake structures, and is also concerned with the transport of sediment in rivers and coastal areas, and the processes of scour and deposition. The hydraulic engineer not only deals with the structural design but also tries to understand and provide solutions to the natural phenomena in which the water - air and soil interact.

Because of all these reasons, field and laboratory studies are necessary in addition to the theoretical studies.

Hydraulic engineering has the following disciplines, (i) Hydromechanics, (ii) Water Resources, (iii) Coastal and Marine Engineering.

In our department, Hydraulics Division provides the following two programmes in graduate level, (i) Hydraulics and (ii) Coastal and Harbour Engineering.
